Maximizing litter size in the bitch

Abstract

When we plan to breed a bitch, one of our main goals is to maximize litter size. Having large litters provides several functions: 1) ensures that there will be enough stimulus from the fetuses to initiate labor; 2) increases the genetic diversity of the litter; 3) helps controls fetal size; 4) maximizes the choice of puppies for clients and breeders; 5) increases socialization activity among the puppies. In order to increase reproductive efficiency we must understand the factors we can influence and those that are predetermined. By making proper choices, veterinarians and breeders can improve their litter statistics.
